The new rules allow for the following:
Full flexibility for setting a project's grace period, repayment profile, and maximum repayment term, subject to a maximum average life of 5.25 years; or
The extension of a project's average life up to 7.25 years, subject to constraints for setting a maximum grace period of 2 years and a maximum repayment term of 14 years.
In this case, the mine will have to be productive two years after signing the contract.
